Cornerstone (Job 38:6; Isaiah 28:16), a block of great importance in binding together the sides of a building. The “head of the corner” (Psalm 118:22, 23) denotes the coping, the “coign of vantage”, i.e., the topstone of a building. But the word “cornerstone” is sometimes used to denote some person of rank and importance (Isaiah 28:16).

Our Lord is called the Cornerstone who was set in highest honor (Matthew 21:42). He is also styled “the chief corner stone” (Ephesians 2:20; 1 Peter 2:6-8). When Zechariah (10:4), speaking of Judah, says, “Out of him came forth the corner,” he is probably to be understood as ultimately referring to the Messiah as the “cornerstone.”
